Discussion Updated for latest aviation discussion below.

Aviation
18z issuance...VFR conditions through about 26.09z followed by
mostly ifr CIGS and visibilties through 26.18z. Lower CIGS and
visibilties mostly from low stratus, patchy fog and heavier precip
in showers and thunderstorms moving across the region Thu morning
after sunrise. Winds will be northwest at 5 to 10 knots through
mid to late afternoon shifting west late this afternoon and
overnight, increasing to 10 to 20 knots mostly during the
daylight hours on thu. 32 ee

discussion... Updated for latest aviation discussion below.

Aviation...

12z issuance... A few patches of MVFR conditions in fog will be
possible over interior areas at the beginning of the period which
dissipate early. Prevailing clear to mostly clear skies today
into this evening will be followed by aVFR ceiling advancing into
the area overnight with a MVFR ceiling developing over interior
southeast mississippi and interior southwest alabama late tonight.

Isolated to scattered showers with a few embedded storms develop
west of i-65 late tonight. Calm to light northwest winds at the
beginning of the period transition to a west to northwest flow at
5 to 10 knots by mid to late morning. A light southerly flow
develops this evening. 29
prev discussion... Issued 423 am cdt Wed apr 25 2018
near term now through Wednesday night ... A shortwave trof over the
coast moves to the new england area and phases with another
system advancing across the great lakes. Meanwhile, yet another
shortwave trof over the central plains advances to the lower
mississippi river valley by late tonight. A surface low associated
with the east coast system will be located over north carolina at
the beginning of the period and lifts off to the north during the
day, maintaining a dry northerly surface flow over the forecast
area. As the central plains system advances toward the region,
another surface low develops near eastern arkansas then advances
into northern mississippi this evening and brings a cold front
into central mississippi. A brief southerly flow develops over the
forecast area this evening ahead of the approaching front
followed by the front advancing into the western portion of the
forecast area late tonight. Will have dry conditions continuing
over the area through this evening followed by slight chance to
good chance pops after midnight along and west of i-65 for
isolated to scattered showers (with a few embedded storms
possible) along the front. Instability will be weak and no strong
or severe storms are expected. 29
short term Thursday through Friday night ... Well defined
southern stream mid level impulse aligned over the lower ms river
valley daybreak Thursday pivots quickly east and northeastward up
across the southern appalachians by evening. This feature brings
a compact area of mid level height falls eastward over the mid-
south resulting in an eastward moving frontal wave of low pressure
over the same areas, extending south and west from the low,
attendant front approaches from the west. Out ahead of the front,
instability remains weak on Thursday in the latest 25.00z weather
models with mu capes less than 500 j kg. Also the latest
probabilities in the short range ensemble assessment on
instability (mu CAPE >500 j kg) are small => (10 to 20%). Even so,
the strength of the energy aloft supports a mention of storms.

Could be some small hail in any of the storms that achieve a
deeper updraft over the interior. The risk of severe weather is
minimal. Due to the quick eastward motion of Thursday's system,
highest rain amounts look to add up to around a quarter inch or
less.

On the heels of Thursday's upper system, another fast moving
shortwave upper impulse exits the southern plains late Thursday
night into Friday morning, and swings east over the northern gulf
coast Friday and Friday night. This system will bring a small
chance of showers through the area on Friday, followed by dry
conditions Friday night. Daily highs and lows look to remain
mostly below seasonal normal.

Long term Saturday through Tuesday ... The upper level trof over
the eastern CONUS Saturday will lift off into the western
atlantic early next week, followed by a medium amplified upper
level ridge building in from the west. The upper ridge is
maintained from the gulf, northward up across the appalachians
Monday and Tuesday. Surface high pressure builds in from the west
over the weekend and strengthens over the mid-atlantic and
southeast into the start of next week. Rain-free Saturday through
Monday. A southeasterly low level return flow will set up across
the region late Monday night through Tuesday as the center of the
surface highs moves over the western atlantic. This should bring a
low end chance of light showers back into the western portions of
the forecast area by Tuesday. With the high more to the east late
in the medium range, temperatures begin to modify to closer to or
slightly above seasonal. 10
marine... Light to moderate northwest winds become west to southwest
today followed by a moderate to occasionally strong westerly flow on
Thursday. A cold front meanwhile approaches from the west and moves
through the marine area Thursday night with a northerly flow
prevailing in the wake of the front through much of the
weekend. 29

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
